Why do some people withdraw messages that have passed a minute?

This is because some mobile phone software allows users to customize the time for withdrawing information, and users can set the time limit for withdrawing information to 1 minute. The user sends a message and reaches the other party's mobile phone within 1 minute. If the user finds that the message sent is wrong within 1 minute, he can withdraw it.
